Patent GB-2105444-A (GB)
Title: Practice projectile
Inventor: SCHONBERG NILS
IPC: F42B10/52
Filed: 1982-09-08
Abstract: This invention relates to a rotation-stabilised practice projectile intended for use with such direct firing weapons as tank mounted guns etc., from which the projectile leaves the barrel at supersonic speed. The projectile according to the invention is so formed that when its speed falls below a certain value it is quickly braked to a stop. In this way the projectile is given a good close range precision trajectory with a short maximum range. This is achieved by forming the projectile as a cylindrically-shaped body (1) of the same caliber as the gun barrel from which it is to be fired, and from the forward end of the body there projects a dowel-like nose (8) which as long as the projectile is in flight at great speed, deflects the surrounding air from the forward end of the projectile. However, when the speed of the projectile has dropped sufficiently, the nose can no longer deflect the air and instead forms eddies of air against the front end of the projectile thereby quickly braking the projectile. The nose 8 may be unscrewed to convert the projectile from a long range practice projectile to a short range practice projectile a tracer is carried at 5. <IMAGE>

Patent GB-2129935-A (GB)
Title: An adaptive filter
Inventor: GLASGOW JOHN ARTHUR
IPC: G01S7/527
Filed: 1983-03-30
Abstract: A received signal which may exhibit frequency variations, e.g., caused by variations of the Doppler shift, is detected by correlating the signal with a number of reference waveforms. The illustrated filter is a digital filter. The signal to be filtered, from a digitizer 5, is sampled and successive blocks of samples are entered into a correlator at 6A. Each such block is correlated in turn with a number of reference waves generated at 7 and placed in turn in the reference channel 6B of the correlator. The output of the correlator, together with information from the reference wave generator 7 and a timer 1 is passed to a phase corrector 8 which calculates, for each correlation, the phase and rate of change of phase of that component of the signal block which correlates with the appropriate reference channel. These phase and rate of change of phase values are stored, together with values denoting the degree of correlation in a signal characteristic store 9. A combiner 10 searches the information in the store 9 for correlation results, from signal block to signal block, which display phase continuity thereby filtering off the remaining information which is attributed to noise. The filter may be used in sonar or acoustic radar systems. <IMAGE>

Title: Apparatus for splash spotting
Inventor: DAVIES NYALL
IPC: G01S13/522
Filed: 1983-06-08
Abstract: Apparatus for spotting a splash produced by a shell or missile entering the sea includes using a radar to obtain signals reflected from the splash and allocating them to cells according to the range brackets into which they fall. The velocity components of the splash are also obtained using fourier transformer and a range velocity map obtained. A target echo will occupy on cell 19, i.e. at one range and one velocity whereas the signals from the splash will occupy a number of cells 27, each having the same range brackets but different velocity spreads. Since the characteristics are different the splash may be distinguished from the target even if it occurs very close to the target. <IMAGE>

IPC: H01J37/32
Filed: 1983-12-07
Abstract: In apparatus including a target 16 having a surface of material to be evaporated; circuitry for establishing an arc on the target surface for evaporating the target material, the arc being characterized by the presence of charged particles and a cathode spot which randomly migrates over the target surface, a confinement ring 24 contacts and surrounds the target surface, the ring being composed of a material such as boron nitride having (a) a secondary emission ratio less than one at the mean energies of the charged particles of the arc and (b) a surface energy less than that of the evaporated target material to thereby confine the cathode spot to the target surface. Further, the secondary emission ratio of the confinement ring is preferably less than that of the target. If the target is permeable, a permeable ring may also surround the target for effecting substantially uniform evaporation from the target. The confinement ring may also be employed as a cover for a permeable ring to prevent migration of the cathode spot onto the permeable ring during initial clean- up of the target. <IMAGE>

Title: Process and apparatus for removing ink from wastepaper
Inventor: SHIOIRI AKIRA
IPC: D21C5/02
Filed: 1985-09-06
Abstract: Wastepaper is treated by a ink-removing process in which an aqueous wastepaper pulp slurry is introduced into a treating vessel, air is blown into the wastepaper pulp slurry preferably through a number of air-blowing orifices formed on a peripheral surface of at least one horizontal cylinder located in the bottom portion of the vessel to absorb ink particles floating in the wastepaper pulp slurry by air bubbles ejected from the orifices and rising toward the wastepaper pulp slurry surface. The resultant ink-absorbed froth is then removed. In this process, air is blown in an amount satisfying the relationship (I) G/L>/=5.0 (I) wherein L is the volume (m3) of the wastepaper pulp slurry in the treating vessel and G is the total volume (Nm3) of the air bubbles blown into the vessel, to promote the contact of the air bubbles with the ink particles in the wastepaper pulp slurry.

Title: Hand operated pruners and the like cutting and gripping tools
Inventor: CRASKE WILLIAM JOHN
IPC: A01G3/02
Filed: 1986-03-06
Abstract: A garden pruner provides two modes of operation. The first or direct mode closes the cutting blades 2, 3 by scissors action in which the clenching force of the hand is directly transferred to the cutting blades 2, 3. The second or ratio mode introduces mechanical amplification to the pruner action so that the force provided at the cutting blades 2, 3 is considerably increased for the same hand grip as before. An adjustable break-clutch 17, 18 is employed to automatically change the pruner action from the first to the second mode if the effort required to sever a plant stem placed between the blades is greater than can be achieved by the hand grip of the operator while the pruner is operating in the first mode. This principle may also be applied to hand tools for other purposes which have cutting or gripping blades. <IMAGE>
